The acting Notary Public advised the persons appearing that unless the powers of
attorney presented to him have notarially certified signatures and notarial
confirmations (or equivalent evidence, e.g. by means of a certified extract from
an official Commercial Register, is provided) of the existing of and the
representation power for legal entities purported to be represented, the Notary
cannot examine neither the authenticity of the signatures nor the representative
capacity of the persons who purported to have signed the powers of attorney. The
Notary does not assume any liability as to the validity and scope of the powers
of attorney presented, which do not conform with the requirements mentioned
above, and of the powers of attorney, which are only alledged (powers of
attorney of the other partners in Madaus Vermogensverwaltung GbR and Vogele
GbR).

Nevertheless the persons appearing insisted on the immediate notarization and,
unless stated otherwise above, released each party from submitting subsequently
certified powers of attorney or other documents evidencing or supporting the
representative capacity.

The acting Notary advised the persons appearing that a notary who or whose
partners in the law firm have formerly acted as legal advisors to one of the
parties involved in the matter to be notarized would not be entitled to take
office as a notary in the matter at hand pursuant to (S) 233 Sect. 1(4) of the
Introductory Act of the Canton Basel-City relating to the Swiss Civil Code which
provision corresponds with the so-called "Vorbefassungsverbot" under the German
Act of Notarization ((S) 3 Sect. 1(7)). The acting Notary states that he himself
and his firm have not been involved in the matter at hand in the meaning of said
provisions. By approving the present Agreement, the Parties hereto shall confirm
such statement of the acting Notary.

The persons appearing requested this Deed including its Exhibits to be recorded
in the English language. The acting Notary Public who is in sufficient command
of the English language ascertained that the persons appearing are also in
command of the English language. After having been instructed by the acting
Notary, the persons appearing waived the right to obtain the assistance of a
sworn interpreter and to obtain a certified translation of this Deed including
the Exhibits hereto.


The persons appearing, acting as indicated declared with request for
notarisation the following:

Sec. 4

Vendors's Representations and Warranties

Vendor represents and warrants that the statements made under Sec. 1 including
Exhibits 4 A and 4 B and the following declarations are correct:

1. The Company is a legally effective existing company with limited liability
according to the provisions of the German Code for Companies with Limited
Liability ["Gesetz betreffend Gesellschaften mit beschrankter Haftung"]
entitled to run its business in the present form.

A current version of its valid Articles of Association of the Company (as
amended on 14 August 1998) is attached hereto as Exhibit 5 for
---------
identification purposes only.

The extract from the commercial register as attached hereto as Exhibit 6
---------
reproduces the current legal position of the Company completely and
correctly except that Mrs. Jutta Griebel is no longer managing director and
Caspar Graf von Stauffenberg has been appointed managing director.

The other Group Companies are legally effective existing companies in the
legal form as indicated in Sec. 1 para. 3 and Exhibit 4 B.

2. The individual vendors as listed under Sec. 1 para. 2 and Exhibit 4 A hold
their shares in the Company as sole proprietors in their own name and on
their own account. The Shares are not subject to any rights of third
parties, and there are no claims to the granting of such rights or to the
transfer of shares. In particular, the Shares are not attached or pledged
(except for a pledge granted to Dresdner Bank AG on the basis of a Loan
Agreement dated 14 August 1998 (and the Attachments 4-8 thereto) (the Loan
Agreement and its Attachments 4-8 hereinafter collectively referred to as
"Dresdner Bank Loan Agreement") (a copy of the Dresdner Bank Loan Agreement
is attached hereto as Exhibit 7 for identification purposes only), provided
---------
that such pledge does not constitute a security for loans other than those
loans shown or otherwise referred to in the Annual Financial Statements as
defined under para. 4 below) or charged with a sub-participation or
otherwise. The Shares are not subject to execution of a last will or to the
conditions of an estate of prior and succeeding heirs.

The Company and MAP KG respectively hold their shares in the Affiliates as
indicated in Sec. 1 para. 3 above and Exhibit 4 B as sole proprietors in
their own name and on their own account. These shares are not subject to any
rights of third parties, and there are no claims to the granting of such
rights or to the transfer of shares. In particular, these shares are not
attached or pledged, (except for the Dresdner Bank Loan Agreement, provided
that such pledge does not constitute a security for loans other than those
loans shown or otherwise referred to in the Annual Financial Statements as
defined under para. 4 below) or charged with a sub-participation or
otherwise.

3. Silent participations or loans with profit participation regarding the Group
Companies' profit do not exist and no shares, stock options (except as
provided on behalf of Kleinwort Benson European Mezzanine Fund II by
agreement dated 14 August 1998 and on behalf of Caspar Graf von Stauffenberg
in his employment agreement, which options, however, have both been
terminated before the date hereof) warrants or derivative securites, no
other equity securities and no debt or convertible securities have been
issued with regard to the Group Companies, except as listed in Exhibit 8 or
---------
in Sec. 8 below.

4. The consolidated annual financial statements ["JahresabschluB"] of the
Company as of 31 December 1999 (hereinafter referred to as "Annual Financial
Statements" and "balance sheet date" respectively) which have been audited
by Haarmann, Hemmelrath & Partner GmbH Wirtschaftsprufungsgesellschaft
Steuerberatungsgesellschaft, Munich, on 14 April 2000 have been prepared
with the diligence of a prudent businessman on the basis of proper
accounting and in accordance with International Accounting Standards
("IAS"). These regulations and principles were applied unchanged and
consequently as of 31 December 1998 when consolidated annual financial
statements according to IAS had been prepared for the first time. All risks,
decreases in value and losses recognized when preparing the Annual Financial
Statements were considered by applying adequate depreciations, value
adjustments and reserves. The Annual Financial Statements are complete,
correct and present a true and fair view of the assets, liabilities, profits
and losses of the Company and the Group Companies as of the balance sheet
date and during the financial year ending on the balance sheet date. To the
best knowledge of Dr. Stefan Rolf Madaus and Mr. Harald Vogele, neither the
Company nor the Group Companies had any contingent liabilities as at the
balance sheet date that were not disclosed in the Annual Financial
Statements.

5. As of 31 December 2000, the "liabilities due to banks" minus "cash" of the
Group Companies as defined in Exhibit 9 A did not exceed DM 30,200,000 (in
-----------
words: German Marks thirty million twohundredthousand). Since then, the
Group Companies have not incurred any bank liabilities outside the ordinary
course of business and substantially outside the budget in Exhibit 9 B (i.e.
-----------
not exceeding the budgeted amount by more than 5 %).

6. The Group Companies have been continued since the balance sheet date in the
scope of the normal and proper course of business. Since then, there have
not occurred or been carried out any extraordinary business or legal
transactions. Neither has there occured any event which solely or together
with other events has had a material adverse effect on the profit situation
of the Group Companies. To the best knowledge of Dr. Stefan Rolf Madaus and
Mr. Harald Vogele, since the balance sheet date, defects or losses which -
in contrast to the current consolidated forecast for the Company's business
year ending on 31 December 2000 as enclosed as Exhibit 9 B -, solely or
cumulative, considerably negatively affect the Group Companies or their
financial standing have not occurred.

7. Vendor and/or employees and/or consultants of the German Companies do not
own any protection rights on the basis of which the German Companies may be
required to pay licence fees or the worldwide business of the German
Companies may be hindered or prohibited, except for such protection rights,
if any, of present or former employees of the Company based on the German
Act on Employees' Inventions ["Arbeitnehmererfindungsgesetz"]. All
intellectual property rights or licences to such rights necessary to run the
German Companies' business in its present form are held by the Group
Companies, however, provided that MAP KG (formerly: MAP Medizintechnik fur
Arzt und Patient GmbH) has entered into a license agreement with Mr. Peter
Griebel dated 14 August 1998 with regard to various inventions and know-how
related to out-patient diagnostics of sleep disorder ("MESAM"/"POLYMESAM").
A copy of this license agreement is attached hereto as Exhibit 10 for
----------
identification purposes only.

8. Except as set out in Sec. 1 para. 3 and Exhibit 4 B the Company does not
hold an interest in any other business organisation.

Company is in possession of all permits necessary for the conduct of its
business and has fully complied with all material terms thereof.

10. Except as disclosed in Exhibit 11 or provided for in the Dresdner Bank Loan
----------
Agreement the Company has full and unencumbered title to all movable assets
employed in its business, and, to the best knowledge of Dr. Stefan Rolf
Madaus and Mr. Harald Vogele, all such assets are, beyond normal wear and
tear, in good repair and full working order. To the best knowledge of Dr.
Stefan Rolf Madaus and Mr. Harald Vogele, all stocks held by or on behalf of
the Company are stored in suitable conditions, and none of them have become
unusable or are of an age or condition to reduce their value below book-
value.

11. To the best knowledge of Dr. Stefan Rolf Madaus and Mr. Harald Vogele, all
material contracts to which the Company is a party are in full force and
effect, and no party thereto is in default of its performance thereunder,
except that at explicit request of ResMed, Dresdner Bank has up to now been
informed neither about the transaction consummated by this Agreement nor
about the Dutch Transaction. The conclusion or performance of this Agreement
do not constitute a breach of, and will not entitle any third party to
terminate, any such contract, except as provided for in the Dresdner Bank
Loan Agreement.

12. The Company has not received any investment grants or other subsidies from
any public authority which may become repayable as a consequence of the
conclusion or performance of this Agreement.

13. To the best knowledge of Dr. Stefan Rolf Madaus and Mr. Harald Vogele, all
of the assets of the Company have been kept fully insured at all times in
accordance with sound commercial principles. All premiums in respect thereof
have been fully and timely paid. There are no outstanding claims by the
Company against any insurer.

14. The Company is not a party to and has, to the best knowledge of Dr. Stefan
Rolf Madaus and Mr. Harald Vogele, not been threatened with any legal,
administrative or arbitral proceedings in any jurisdiction, except the
lawsuit with Hoffrichter Medizintechnik GmbH with regard to the infringement
of intellectual property rights by Hoffrichter, whereby Hoffrichter has
threatened the Company and/or MAP KG with a counterclaim regarding an
alleged infringement of intellectual property rights by the Company and/or
MAP KG. No product liability claims against the Company are pending or have
been raised and resolved other than by a rejection of such claims during the
previous three years.

15. To the best knowledge of Dr. Stefan Rolf Madaus and Mr. Harald Vogele, the
Company has at all times complied with all environmental legislation and
administrative rulings applicable to its business. To the best knowledge of
Dr. Stefan Rolf Madaus and Mr. Harald Vogele, all assets, including all
premises, used by the Company in the conduct of its business are free of
environmental pollution.

16. Exhibit 12 sets out accurately relevant particulars of officers, directors,
----------
managers and key employees currently employed or contracted to be employed
by the Company; the Company has no works council ["Betriebsrat"] and the
Company is not a party to collective bargaining agreements. The Company has
not granted any pension benefits to any person. The Company has fully paid
all social security contributions as and when they were required to be paid.

17. To the best knowledge of Dr. Stefan Rolf Madaus and Mr. Harald Vogele, all
contracts and other transactions between the Company on the one hand and any
of the Group Companies, any of its shareholders or any person who is a
member of the immediate family of such shareholder on the other hand have
been concluded and carried out on terms appropriate to contracts or
transactions with unrelated parties on an arm's length basis.

18. The Company has fully paid all taxes and duties payable by it and has, to
the best knowledge of Dr. Stefan Rolf Madaus and Mr. Harald Vogele, made
full provision for all such taxes not yet assessed and due. The Company has
punctually filed all tax and customs returns when due, and the contents of
such returns are to the best knowledge of Dr. Stefan Rolf Madaus and Mr.
Harald Vogele complete and accurate. No fiscal or customs authority has
notified the Company of any alleged inaccuracy of such returns or has
threatened the Company with legal or administrative proceedings in respect
thereof.

It is clarified that Vendor neither represents or warrants nor assumes any
liability for

Companies,

- - the ability of Buyer to achieve certain tax structures or to apply certain
accounting principles with regard to the transaction contemplated herein
under tax and/or commercial law, in particular to achieve a "step-up" for

U.S. GAAP, and

- - any consequences arising from the Dutch Transaction.
